Wow, not only did I like watching your naked wife but she actually gave me a hardon, would love to see and participate in the defilement of all her holes and beautiful curves.
You should whisper in her ear and tell her what a little slut she is for sucking a strangers cock in front of you. She'll probably try to respond but given the circumstances she'll probably just whimper and slobber all over it instead while she gives you a side eye.
